A large storage tank, open at the top and filled with water, develops a small hole in its side at a point 16.0 m below the water level. The rate of flow from the leak is found to be 2.50 times 10^-3m^3/min. Determine the speed at which the water leaves the hole. Determine the diameter of the hole.

(a) v = (2gh)^1/2
= (2 * 9.8 * 16)^1/2
= 17.70 m/s

rate of flow= AV = pie R^2 * 17.70 = 2.50 * 10^-3

R= 0.0067 m
